Degradation of parathion in the rat
Biochemical Pharmacology, 1969Abstract Examination of urinary metabolites of 32 P- and 35 S-parathion orally administered to rats confirmed that initial metabolism of parathion involved activation to paraoxon and degradation to diethyl phosphorothioic acid. Sulfur detached in the activation reaction was excreted as inorganic sulfate.

Toxicokinetics of parathion in the rabbit
Archives of Toxicology, 1988The plasma kinetics of parathion were studied in rabbits after i.v. administration of a dose of 1.5 mg/kg and oral administration of 3 mg/kg. The time course of parathion plasma levels administered intravenously followed a three-compartment kinetic model statistically, whereas when administration was oral, the optimum kinetic model proved to be two ...

Effect of serum-parathion interactions on cutaneous penetration of parathion in vitro
Food and Chemical Toxicology, 1985The effect of serum and serum fractions on the cutaneous penetration of [35S]parathion from surface deposits or adsorbed formulations was determined. The total quantity of [35S]parathion which penetrated pig skin was significantly greater when the receptor fluid was whole swine serum or the 500 or 10,000 MW retentate from ultrafiltration of the serum ...

Toxicity of parathion, systox, octamethyl pyrophosphoramide, and methyl parathion in man
Toxicology and Applied Pharmacology, 1969Abstract Experiments in human beings were undertaken to determine the levels of minimal toxicity of parathion, systox, OMPA, and methyl parathion. The study of parathion demonstrated that the level of minimal toxicity is 7.5 mg per day. Between 6.75 and 7.125 mg per day of systox produced minimal toxicity.

Accelerated parathion degradation in soil by inoculation with parathion-utilizing bacteria
Bulletin of Environmental Contamination and Toxicology, 1977The use of microorganisms for the decontamination of pollutants in the environment is only a recently acknowledged feasibility, even though sewage and certain industrial liquid wastes are routinely treated biologically. Nearly all of the research has been directed toward the use of microbial preparations for the cleanup of oil spills (BERNER et al ...

Parathion poisoning in children
The Journal of Pediatrics, 1953Summary 1. Cases of parathion poisoning in children have been presented; one, a fatality. 2. These accidents were due to gross carelessness on the part of their parents. 3. Specific treatment is available and may be lifesaving if properly administered.

Reductive transformation of parathion and methyl parathion by Bacillus sp.
Biotechnology Letters, 2007Based on the results of phenotypic features, phylogenetic similarity of 16S rRNA gene sequences and BIOLOG test, a soil bacterium was identified as Bacillus sp. DM-1. Using either growing cells or a cell-free extract, it transformed parathion and methyl parathion to amino derivatives by reducing the nitro group.

Archives of Pediatrics & Adolescent Medicine, 1963
To the Editor: In the February, 1962, issue of Diseases of Children, Page and Verhulst described a specific drug, pyridine-2-aldoxime methiodide (2-PAM) for the treatment of the organophosphate poisonings. This drug reactivates the phosphate bound acetylcholinesterase.
